WINDOW-SCREEN.

Specification of Letters Patent.

Patented Sept. 15, 1914..

Be it known that I, HUGH F. LATIMER, a citizen of the United States, residing at Hyattsville, inthe county of Prince Georges, and State of Maryland, have invented certain new. and useful Improvements in Window-Screens, of which the following is a specification.

My invention relates to improvements in window-screens and fittings therefor.

The object of my invention is to provide means whereby a window may be covered to its full extent with screening, while at the same time such screen is so arranged as to allow thelower half to be raised and lowered to permit access to the window or to the outside blinds. V

' A further object of my invention is to provide a set of fittings for screens to be hung as above indicated, whereby such fittings may be made and sold' as hardware specialties andmaybe fitted to any suitable screen.

With the above general object in view my invention consists in the features, details of construction and combination of parts which will first bedescribed in connection with the accompanying drawings, and then particularly pointed out in the claims.

In the drawings: Figure 1 is a perspecside screen embodying my invention; Fig;

showing one a employed by me;

2 is asectional view of the same; Fig. 3 is a perspective view of one of the hanger rods employed in this construction; Fig. 4: is a detail sectional view showing the meeting edges of the upper and lower screens; Fig. 5 is a front elevation of a window provided with an inside screen embodying a modified form of my invention; Fig. 6 is a sectional view of the same; Figs. elevations of a modified form vice in different position; Fig. 10 is an enlarged detail view, partly in section, of said hanger device; Fig. 11 is a section of the meeting rails of an upper and lower screen of -hanger deof the same; and Fig. 13 is a perspective view of the latch striker plate;

Referring to the drawings,

frame, and B and G are the upper and lower windowsashes respectively; Allthis part of the. construction is old and well known and needs'no especial description.

} sockets in the window frame.

7, 8 and9 are detail form of locking mechanism. Fig. 121s a front elevation v p curing A is a window D isa lower window screen arranged in a suitable manner to slide vertically in the window frame, as, for example, by providlng guiding strips in the usual way, one of which is shown at d inFigI 1. The upper .screen is indicated at E and normally rests in the same vertical plane with the lower screen. The upper screen is supported in a manner to permit it to move outward when the lower screen is moved upward,

whereby when the lower screen is raisedto its full extent it is behind the upper screen. ln order to support the upper screen and yet. allow this displacement of the upper screen, a suitable supporting means is provided. In the construction shown, for eX- ample, in Figs. 1 and 2 this supporting means comprises two rods, F and G, each having both of its'ends cranked as indicated in the drawings, the said rods being journaled in suitable bearingson the upper screen and having their ends inserted in In the example shown these sockets may be merely holes bored in the easing, into which the ends of the rods are inserted by slightly bending or arching the rods, whose resiliencywill permit this to be done.

In order to permit the upper screen to rise slightly upward as it swings outward,

a clearance space must be provided between the top of the said upper screen and the under surface of the upper part of the window frame,.and this clearance space i obtained by terminating the upper screen slightly. short of'the top of the window frame and filling the space in the plane normally occupied by the screen with a strip H. In order thatthe upper screen may move automatically out of the plane of the lower screen by the mere act of lifting the lower screen the meeting edges of, the two screens and the meeting edges of the upper screen and the strip H are suitably formed so that upward movement of the screens causes a displacement of the upper screen in the desired direction; I This. may be done by beveling the said meeting edges as indicated in the drawings, or if desired by seto the edges beveled or rounded strips. In Fig. rthe upper edge of the lower screen is shownprovided with such a separated rounded strip, indicated at I. The operation of the device is as follows: When the lower screen is lifted, the beveled v meeting edges of r. the upper and lower screens cause the upper screen to move out.

Ward from the window s ash, the cranked arms of the rods F and G causing the said upper screen to move in parallelismwith. the window sash. The continued upward movement of the ;lowe r screen causes it to pass behind the upperscreen, therebygiving access to the window sashes or to lhe outside blinds. Upon pulling down the lower "SCIQGII to its normal position the up per screen will drop into place by its own weight.

In the construction shown 'in' Figs." 5 and 6 the upper screen 'is hung at the upperend' only, the lower endofxthe upper'screen being normally locked 'to-the upper: endOf the 4 lower screen by an suitable locking means. The locking device is placed on that'side of rangement wherethe screens are assumediite the screens which isto betowardthe inside of the house; Figs. 5 and" 6 show an ar be on theinside of the :Window, the latch plate K of the locking device being attached to the bottom-rail of theiupper screen: Figs. 11 and 12 illustrate an arrangement of locking means where. the screensare to be on the outsidelof the window. In jv the example shown, the'locking'meanscomprises a flat :screen', which is recessed behind the'plate to plate K fastened-to thetop rail 'ofthe'lower' accommodate aswinging "latch lever 7c pivoted to the plate andhaving one end arranged to-enter an openin'g ktin a striker plate Kfastened to theloweredge of the upper screen, the other end ofthe'lever being bent outward togform a handle 70 I When the'lower screen is to be raised, the

latch lever is swung to .withdraw its latch end'from the opening in thestriker j plate and 'belowthe'beveled upper edge of the"lower "screen. The lower screen. may

\ thenbe raised, the upper screen being swung outwardly, WVhen thescreensare to be in side the window, itisordinarily best to in-- vert thearrangementof the described parts I of the latching device, this being indicated 'in-Figy5.

In the modification shown inFigsl 5 and 6, the upper screen isnot supported by a rod extending; entirely across the screen, but by a A pair of hangers, each consisting" of a link L having its ends cranked in opposite directions, as shown Fig. 7 one ofisaid ends havinga head as indicated at'Z. To-the head of the window frame is secured a top-hanger -plate M having a journal bearing m ijn jwhich the headed end ofthe hanger L is l V rotatable. To the upper screen framek'is secured a lower hanger plate N which also is it provided with a journal bearing for the U unheaded. arm "of th'e'han'ger L. 7 .By this an rangement, theupperscreenis free to swing p ujavwrardandawayfrom the normal positlon,

s V v as the lower screen rises.

P :bei 's e e 1 I by accident.-

In "order to allow of "the convenient flre-' moval of the upper screen, thehanger de vices may ben-iade set-hat the hanger L may r be removed from oneof the j ournal be'arings on each side, and thls constitutes -an i npor- 7o tant feature of -my' invention. In lts specific pref-erred form, the journal 'bearings of the top hanger-plates M are slotted, as indi gatedin Fig.1 l'O and the headed arm of the hanger L is flattened in cross-section so that when it is rotated in thebearing to theiposij tion "shown inFig; -l0 it may he slipped out of the said journal bearing, but at, any other position its. diameter is too: great to: allow it to pass throughthe slot. Furthermore, the positionwhentheminimum diameter of the Y arm coincides with the 'slot is such that/the .upper screen would never reach such posi V "-ti'on'in the normaljoperationof'?the screens,

so that there isjno' danger ofthe hangers Lif ss fromitheirjtop hanger plates 3 Inorder toprevent any 'danger of thefuppe'rscreen being shaken by'thewindand thereby rattling, a 'suitable light spring pres sure may be maintained on the ,uppers'creen, for example .by having a' coiled sprlngP part ofthehanger as indicated inFig. 5.; 9'5
